KEYLESS PADLOCK.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed April 25, 1914. Serial No. 834,484.

To all whom it may concern:

Be it known that I, JOSEPH P. Holmes, a citizen of the United States,residing at Gasper, in the county of Natrona and State of \Vyoming, haveinvented certain new and useful Improvements in Keyless Padlocks, ofwhich the following is a specification.-

The object of my invention is to provide a keyless' padlock of theermutation type, comprising few parts su antial in construction and allarranged in such a manner that the lock cannot be opened without theproper combination, and one which presents the parts in such a mannerthat they can be separated by violence only by the exertion ofsufficient force to break the lock strucprovide a lock havfullydescribed in connection with the accompanying drawing and moreparticularly pointed out in the appended claims.

In the drawing:-Figure 1 is a view in elevation of the lock with thecover plate removed to better illustrate the -arrangement'of theoperating parts. Fig. 2 is a view in side elevation of the completepadlock. Fig. 3 is a view in transverse section through the body of thelock to illustrate the mounting of the tumbler disks. Fig. 4 is a viewsimilar to Fig. 3 with the tumbler disks also in section.

The body 1 of the lock is cored out at 2 to form a case. A shackle 3 ispivoted by a pin 4 to the body portion and a shackle opening 5 isprovided in the body 1 to receive the free end of the shackle 3. A boltslot 6 is formed tangentially from the coredout portion 2 andcommunicates with the shackle opening 5.

A cover plate 7 is provided to be received againstthe open side of thebody 1 and is held in place thereon bv rivets 8, 8. A lock bolt 9 ismounted to slide in the bolt-slot6 in such relation that its outer endextends through the slot into the shackle opening 5 and at the inner endthis lock bolt has an arm 10. The shackle 3 on its free end has a boltnotch 11 and when the bolt 9 is moved to its one extreme position theouter end thereof is received in this notch 11.

The cored-out portion 2 of the body 1 is made circular so that the casethus provided is circular, and an opening 13 of less diameter than thecored-out portion 2 is formed through the side of the body. A similaropening 12 is provided through the cover plate 7 and when this coverplate is in place on the body of the lock the two openings are inalinement. The tumbler disks 14, 15, 16 and 17 are mounted in thecoredout portions-2 and these disks have openings provided through theircenters. The disks 14 and 17 which are the outer disks as mounted in thecored-out portion are made with their bodies of a suflicient radialwidth that faces 23 and 26 respectively are presented to be visiblethroughthe openings 13 and 12, and disks 15 and 16 are made of aslightly greater bodily width so that a portion of the face of the bodythereof will be presented at 24 and 25 through the openings of the disks14 and 17.

The tumbler disks 14, 15, 16 and 17 have the radial slots 18, 19, 21,and 22, respectively, formed in their outer edges. The faces 23, 24, 25and 26 of the disks which are visible through the openings 13 and 12,are marked off in dial figures as better shown in Figs. 1 and 2, thusmaking it possible to retain a record of the positioning of the slots18, 19, 21, and 22, even after the lock has been assembled by placingthe tumbler disks in the cored-out portion and then securing the coverplate 7 in place. It is the intention that these slots shall all bebrought into registry when it is desired to open the look and that thetumbler disks may be more readily turned in the cored-out portion theedges thereof adjacent the opening are milled or knurled to present arough surface which mav be gripped with the fingers.

The bolt slot 6 is made stepped as at 20 at its inner end, and when thebolt is in the position shown in Fig. 1 with the arm 10 thereof engagingwith the periphery of one or several of the tumbler disks this bolt isheld in a position that the outer end is engaged against displacement inthe notch 11 of the shackle. When it is desired to withdraw the boltfrom the notch in the free end of the shackle to release this shackle,the tumbler disks are turned to a relation that the notches 18, 19, 21and 22 are brought into registry, and then by rotating the several diskscollectively to bring the registering notches beneath the arm. of thebolt and exerting a pulling free end of the shackle 3, the bolt 9 willbe caused to be swung inarelation that the arm 10 thereof enters thenotches. With the arm 10 of the bolt S) in the notches, the tumblerdisks are movedcollectively in a turning path clockwise as the parts areillustrated in Fig. 1 and the bolt 9 as it is disengaged from theshoulder of the slot 43 is then carried to the position indicated by thedotted lines and the shackle is released. When the lock is to a ain befastened. the free end of the shaede is closed into the shackle openinga and anti-clockwise movement is given to the tumbler disks to cause theend of the bolt 0. to be engaged in the notch 11 of the shackle, then nma further inward.movementof the free en of the shackle the bolt is swunto a position with the inner end thereo engaging the shoulder 20 of the'slot (3 and the arm 10 is released fromthe notches of the tumbler disksso that these disks may beindependently turned to upset the releasingcombination.

When it is desired to change the combination as indicated by thedials atwhich the bolt may be thrown, the 17 may be interchanged in theirpositioning within the body 1 of the-lock, and .to give wide and variedscope to the combination of the lock as turned out at the factorytheslots 18, 19, 21, and 22 may be stamped or:

cut at any point around the periphery of the tumbler disks and thuschange the combination at which the slot of each disk comes i1nt lregistry with the slot of the remaining C 15 I.

\Vhile I have herein shown and described one specific form of myinvention, it will be understood that slight changes might be made inthe form and arrangement of parts without departing from the spirit andscope of my invention, and hence I do not wish to be limited theretoexcept for such limitations as the claims may import.

1 claim:-

1. lock of the type described comprising a case having an openingtherethrough, a shackle. shack e holding means, a plurality of tumblerdisks rotatably mounted within the casing to be accessible through saidowning so that each can be moved manna ly to bring the disks combinationat which the shackle holding means is released.
